It is found that the GMSL is less dispersive compared to conventional microstrip lines, and also provides a wide range of characteristic impedance values as a function of the groove width. Increasing the groove width of the microstrip structure can also reduce the dielectric and conductor Losses of the GMSL.193165 bytesapplication/pdfeng©2000 IEEE.
